MANUFACTURING METHODS OF LAVER EXTRACT AND BUGAK CONTAINING PORPHYRAN FROM UNUSED LAVER

A preparation method of healthful fried laver using waste laver and is provided to enhance the functional properties of laver and promote its consumption. A preparation method of healthful fried laver using waste laver comprises the steps of: (a) making a high-quality laver extract from waste laver; (b) making porphyran by using the laver extract; and (c) coating dehydrated laver with glutinous rice paste made of the laver extract, sprinkling porphyran powder on the glutinous rice paste, and then drying it. The step (a) comprises; heating the dehydrated laver in refined water; filtering the hydrothermal extract, adding 1% of diatomite and 5% of activated carbon to the filtered extract; and performing centrifugation at 15000rpm for 10min to remove coloring substances and odor. The step (b) comprises: heating the laver extract to obtain a 25X concentrate; centrifuging the concentrate at 3000rpm for 10~30min to separate supernatant; putting alcohol(95%, about 3times the amount of the supernatant) in the supernatant, settling for 24hr to separate the crystalline supernatant, and filtering it; and washing the filtrate with alcohol(twice the amount of the filtrate) three times, followed by lyophilizing.
